Mr Bailey said that the new government fully supported the project and any rhetoric coming from the sidelines suggesting anything different is a clear misrepresentation of the facts.

"This government is committed to working closely with industry and business to create jobs and grow the economy," Mr Bailey said.

"Building vital infrastructure in Queensland, such as the long anticipated Toowoomba Second Range Crossing, is integral to this.

"I want to assure Queenslanders that the project will go ahead under this government.

"Treasury's commercial advisory unit, Projects Queensland, will continue with its work on procuring the project," he said.

Three consortia will submit their proposals today.

Three consortia, comprised of local, national and international contractors, operators and financiers were shortlisted to participate in the Request for Proposals phase of the procurement process in late September 2014.

They were chosen following their demonstrated capacity and capability to deliver on a project of this magnitude and recent relevant experience on various infrastructure projects.

The Toowoomba Second Range Crossing will stimulate economic development in the Toowoomba and Lockyer Valley areas and is expected to create more than 1,800 full time equivalent jobs during the three year construction phase.

"It's an important road safety project with the added bonus of providing jobs at a time when jobs and job security are more important than ever," Mr Bailey said.
